Abstract
Experiments were carried out in a pilot scale CFB reactor with Meat and
Bone Meal (MBM) blended with three coals. MBM has high Cl content, which
produces fouling and corrosion in superheaters. Coal ash contains
protective elements (Al, Si and S) that are able to trap alkalies, and
the HCl that is released does not condense on superheaters. The goal of
the study was to select the most protective coal so that the portion of
MBM in the feedstock could be maximised. South African coal, with
highest content of reactive aluminosilicate, provided more protection
against chlorine deposition than did Polish and German coals. Alkali
aluminosilicate formation was the main alkali sequestration path,
dominating over sulfation.
